Hey all, I was just wondering if anyone else has encountered this error attempting to upgrade to Windows 10? My machine is dual-boot Windows 7 64-bit Ultimate and Linux. The boot drive is formatted to GPT and my Windows 7 is being marked as Genuine via WindSLIC. Grub 2 is handling the booting process. Upgrading Windows 7 to Windows 10 proceeds okay up till the point at which the machine reboots for the first time. This big circular progress dial thing displays on the screen for about a second and then the machine reboots again and returns to the normal Grub bootloader. When I return to Windows 7 and login I get a message along the lines of: "Error 0x80073b92 - 0x2009 Installation failed during SAFE_OS phase. Error during PREPARE_ROLLBACK" I did some googling of this issue but none of the answers make much sense. I tried disabling my anti-virus (BitDefender). I don't have any USB drives or other USB devices attached besides my keyboard. Has anyone else run into this issue?
